<span>1. Even though the Greeks did not rely on a systematic study, what method did they use to begin to know the world? <u>Observation</u>.
They would observe the world around them and base their conclusions based on such observations.

If PQRS is a rhombus, which statements must be true

astraxan [27]

Answer:

B, D, E and F are correct.

Step-by-step explanation:

B - PQ is parallel to RS. This is true as opposite sides of a rhombus are parallel.

D - PQR is supplementary to QPS. Two angles are supplementary when they add up to 180 degrees.

E - PR is perpendicular to QS. This is true because the diagonals of a rhombus bisect each other at right angles.

F - PS is parallel to QR. This is true as opposite sides of a rhombus are parallel.

SOMEONE HELP!

enyata [817]

Answer:

see explanation

Step-by-step explanation:

Since the denominators are like, add the numerators leaving the denominator

= $\frac{x+4+x-1}{x-2}$

= $\frac{2x+3}{x-2}$

We require the denominators to be like before we can add.

factor x² - 4 as a difference of squares

x² - 4 = (x + 2)(x - 2)

Expressing as

$\frac{x^2-6x}{x+2}$ + $\frac{2x-12}{(x+2)(x-2)}$

multiply the numerator/denominator of the first fraction by (x - 2)

= $\frac{(x-2)(x^2-6x)}{(x+2)(x-2)}$ + $\frac{2x-12}{(x+2)(x-2)}$

Expand and simplify the numerators, leaving the denominator

= $\frac{x^3-6x^2-2x^2+12x+2x-12}{(x+2)(x-2)}$

= $\frac{x^3-8x^2+14x-12}{(x+2)(x-2)}$

At the city museum, child admission is $6.20 and adult admission is $9.40. On Thursday, 163 tickets were sold for a total sales

Tju [1.3M]

<h2>Systems of Equations</h2>

To form a system of equation from a word problem, we must recognize different variables to form different equations.

<h2>Solving the Question</h2>

Let <em>a</em> represent the number of child tickets.

Let <em>b</em> represent the number of adult tickets.

We're given:

1a = $6.20
1b = $9.40
a and b in total is 163
Total sales = $1221.80

Because we're given that a and b in total is 163, we can form the following equation:

$a+b=163$

We're also given that the total sales made is $1221.80. Because we know that 1a = $6.20 and 1b = $9.40, we can also form the following equation:

$6.2a+9.4b=1221.8$

Here are our two equations:

$a+b=163$

$6.2a+9.4b=1221.8$

<h3>Solving the System of Equations</h3>

We can solve using the method of elimination. Multiply both sides by 6.2 in the first equation:

$6.2(a+b)=6.2(163)\\6.2a+6.2b=1010.6$

Subtract this new equation from the second equation to cancel out <em>a</em>:

$\hspace{10}6.2a+9.4b=1221.8\\- 6.2a+6.2b=1010.6\\\rule{100}{0.5}\\3.2b=211.2$

Solve for <em>b</em>:

$b=66$

Therefore, the number of adult tickets sold is 66.

The profit function is P = 50x + 80y, where x represents the number of chairs and y represents the number of sofas. Using the va

Fantom [35]

Answer: Given the 3 choices in the problem, the greatest profit would be for the final pair (6, 12).

If you input 6 for x in the function and 12 for y in the function, you will get an output profit value of 1260.
P = 50(6) + 80(12)
P = 300 + 960

On these types of problems, there are generally multiple constraints that you have to be aware of. One of the vertices of the possible areas must be (6, 12).
